Create appropriate methods, properties and events that will allow to users to scroll the RadPdfViewer and handle the scrolling events.
Introduce API that will allow to manipulate the scroll bars.

When this feature is implemented it should visualize the bookmarks similarly to in the attached screenshot.

Available in R3 2018 Official Release Version.

Provide public API for accessing document properties such us Title, Author, Subject, Keywords, Creation date, etc...

This mode allows users to show two pages of the document side by side. With the current API this may be achieved by implementing Custom Presenter.

If you search in a very large file and there are no matches of the string you're searching for or the matches are very far from the start (e.g. on the 10 000th page), the search takes a lot of time. The scenario can also lead to a crash.

Consider adding a progress bar showing on which page we're currently searching and implementing possibility to cancel the search.

Due to excessive memory consumption when decoding images, OutOfMemoryException can be thrown when viewing documents with large images inside them. 

Workarounds: 
- Set ExtensibilityManager.MaxImageSize = null. This will skip one resizing step, and could be beneficial in documents containing few large images.
- Use 64-bit process for the client application. This allows the process to consume much more memory. Note that starting 64-bit process while debugging can be tricky, as described in this blog post: https://weblog.west-wind.com/posts/2016/Dec/19/Visual-Studio-Debugging-and-64-Bit-NET-Applications.

Available in R1 2018 Official release version.

OverflowException is thrown while importing document using Helvetica font with custom encoding.

Add support for interactive forms based on the Adobe XML Forms Architecture (XFA). XFA specifies an XFA resource, which is an XML stream that contains the information of the form. The format of an XFA resource is described in the XML Data Package (XDP) Specification. The XFA resource provides most of the information about the form; in particular, all form-related events such as calculations and validations.

Allow passing specific pages (e.g. "1, 4, 6") and more than one page range (e.g. "1-3, 6-7") to the print dialog`s Pages page range.

No images are shown when opening a file.

Hi!

Please extend CreateThumbnail. It is currently defined as:

 public ImageSource CreateThumbnail(RadFixedPage page, Size thumbnailSize)

Well, it works great for thumbnails and display on screen, but for saving bitmaps it is not perfect. 

If I want to change the DPI settings when saving the bitmap it is not possible, also the Pixelformat is not settable because they are hardcoded in CreateThumbnail.

Please extend CreateThumbnail like this:

 public ImageSource CreateThumbnail(RadFixedPage page, Size thumbnailSize, PixcelFormat pixelformat, int DPIX, int DPIY)

By the way, opening up the API behind radFixedPage.LoadContent and the hole drawing/rendering complex would be even better :-)

I'm dreaming of, to be able, only drawing certain layers. Sometimes it helps to see the hole object tree of a page to understand what gets painted over one another.

Thanks! 

Workaround for documents generated with PdfProcessing: When drawing lines using the FixedContentEditor the IsFilled graphic property should be set to false:

RadFixedDocument document = new RadFixedDocument();

Rect rect = new Rect(0, 0, 50, 50);
FixedContentEditor editor = new FixedContentEditor(document.Pages.AddPage());
editor.GraphicProperties.IsFilled = false;
editor.GraphicProperties.IsStroked = true;

editor.Position.Translate(50, 50);
editor.GraphicProperties.StrokeColor = new RgbColor(255, 0, 0);
editor.DrawText("Lines");
editor.DrawLine(rect.TopLeft, rect.TopRight);
editor.DrawLine(rect.TopRight, rect.BottomRight);
editor.DrawLine(rect.BottomRight, rect.BottomLeft);
editor.DrawLine(rect.BottomLeft, rect.TopLeft);

The issue is reproducible only for some specific font files. The characters are displayed as rectangles. This seems to caused by incorrect glyph name and glyph id mapping.

This may allow someone to notify the users.

Represents Free text PDF content.

Since LIB Version 2017.3.925 annotations of type FreeText can be visualized.

Currently, all images are decoded and preserved in RGBA format (32 bits for each pixel). However, there are files that optimize their images by preserving them with 1 bit for each pixel. In WPF we may create monochrome System.Windows.Media.ImageSource that would optimize the performance and memory consumption when rendering such images.

Available in R1 2018 Official Release Version.

RadPdfViewer does not read image resources defined in Form XObject elements.

Introduce support for Sticky Note Annotation.

This exception is thrown because there is field name with special characters which are incorrectly modified during the recalculation process of widget appearances. This exception is thrown in the internal RecalculateMissingAppearances method or in RecalculateWidgetAppearancesOld method.

Expose a button in the UI that can be used instead of Ctrl+F.

Such a button can be currently added by customizing the default toolbar. For more information, check the documentation that describes how to achieve that: https://docs.telerik.com/devtools/wpf/controls/radpdfviewer/default-ui#customizing-the-default-ui
